Comparing todayâs computers to 1995âs “Let me tell you about a computer advertisement from 1993. One company was advertising 9,600-baud modems for as low as $500. Dell was selling a top-of-the-line 486 with a 66MHz processor, eight megabytes of RAM and a 320-megabyte hard drive for $4,400. The single biggest difference is in the hard drive prices. Three hundred dollars got you 80 megabytes, and a one-gigabyte drive from IBM cost more than $3,000. Single speed CD-ROMs sold for $600. Today, if you could buy this hardware, it would cost between 10 and 25% of what it cost two years ago.
